CLdN picks Elomatic’s energy-saving solution for its hybrid RoRo pair

Multimodal logistics provider CLdN has contracted Finland-based consulting and engineering company Elomatic to install tunnel thruster technology on two new roll-on/roll-off (RoRo) vessels currently under construction.

Under the agreement, Elomatic will install its patented Elogrid tunnel thruster grid, an energy-saving device designed to maximize side thrust for better maneuverability.

The solution is expected to reduce additional resistance, lower fuel consumption, minimize noise and vibrations throughout the vessel, and reduce the environmental impact of maritime operations.

According to Elomatic, the Elogrid technology has been found to reduce fuel consumption by 1-2% per thruster tunnel, depending on speed, by reducing flow entry into the bow thruster tunnels at cruising speeds, as well as providing further reductions in associated vibrations.

The installation onboard CLdN’s RoRo vessels is scheduled for the first and second quarters of 2025. This will be the first time Elomatic’s Elogrid technology is installed on RoRo vessels.

The two hybrid 8,000 lane meter RoRo vessels to be equipped with the energy-saving solution were ordered by CLdN in 2022 at South Korean Hyundai Mipo Dockyard (HMD).

In addition to two conventional main engines, the newbuilds will feature two large shaft generators of 6 MW each, which can be used for generating power or for electric propulsion. In full electric mode, the ships will be able to achieve a cruising speed of 16-17 know.

The vessels, which will be delivered in 2025, have a high degree of flexibility allowing for a seamless integration of new fuels, fuel cells and/or battery technology in the future.

Jukka Suvanto, Senior Sales Manager at Elomatic, commented: “Elogrid offers a significant advantage in meeting carbon reduction standards and enhancing fuel economy. These benefits align with Elomatic’s broader strategic goals, which include supporting the shipping industry’s transition toward greener operations.”

David Vermeulen, CTO at CLdN, said: “CLdN is committed to finding new ways to further enhance the performance of its fleet and reduce its environmental footprint. The Elogrid tunnel thruster grid is an innovative solution that fits well with CLdN’s  efforts in remaining the RoRo operator in Northwest Europe with the lowest CO2 footprint and we look forward to deploying our latest 8.000 lane meter G9e new-build RoRo vessels with this technology.”
